Mix Controls

Pixel maps are assigned to a mix using the mix controls. Enter the mix controls by pressing the ‘M’ button in a layer selector.

Each mix has a pixelmapper control panel:

Enable

When disabled, Pixel mapper is shut off for that mix.

Visualisation

By default, there is no video output to the mix from pixelmapper; it only samples pixels and sends the data out over the network. The mapping can be seen live on the mix output by selecting an option in the visualisation menu.

Colour Averaging

Colour averaging calculates the average colour for each cell based on all pixels it intersects.

With Colour Averaging disabled, cells that span across multiple pixels will take the colour of the pixel that hits the centre of the cell. When enabled, all pixels that are overlapped by a cell are averaged together and used to determine the colour for that cell.

Colour averaging can have a dramatic impact specifically with very large or very small cells.

Where cells span across multiple pixels, colour averaging will have the effect of smoothing out colour changes that otherwise would appear too fast. In the case of larger cells, colour averaging is frequently desirable.

Where cells are only only one pixel, colour averaging makes it very difficult to place fixtures perfectly as they not overlap any adjoining pixels. In the case of small, or single pixel cells colour averaging is likely better disabled.

Visualisation Background Image

Sets the level of the background video when using pixelmapper visualisation on the mix. When visualisation is on, an area of the output not covered by a pixelmapper fixture is black by default. Visualisation Background Image allows the video to be show as well as the mapped fixtures.

Pixelmapper and Engine performance

Pixelmapper can add significant load to a system, especially with large and complex maps. This results in a slowing of the video output frame-rate.
